Application led December 26, 1913.

T0 all whom it may concern.'

Be it known that I, SAMUEL S. Rineni., citizen of the United States, and resident of Scranton, county of Lackawanna, and State of Pennsylvania, have invented an lmprovement in Tender-Tank Valves, of which the following is a specification.

The object of my invention is to provide a construction of valve which shall be specially suitable for tanks of locomotive tenders and employed for controlling the supply of water to the injector which delivers the feed water to the boiler.

More specifically, my object is to so construct my improved valve that it shall embody simplicity and durability; that it shall be quick acting and provide a direct flow for the water; that it shall provide a drainage pocket or well below the tank and above the valve controlled port and so constructed that it is adapted for attachment below the bottom of the tank; that it may be operated by a single movement of a lever arm and locked in open or closed positions; and that it shall constitute a positive shut off valve to the water flowing toward the outlet and a check valve to the flow of the water in the opposite direction, whereby the boiler pressure may be employed for blowing the water from the hose connection back through the valve into the tank to avoid damage due to freezing of the water in the hose and associated metal connections.

My invention consists of certain features of construction whereby each and all of the above recited objects may be secured, the said several features of construction being fully described hereinafter and more particularly defined in the claims.

My invention will be better understood by reference to the drawings, in which Figure 1 is a side elevation of a portion of a locomotive and its tender with my improved valve device and connections applied thereto; Fig. 2 is a plan view of my improved valve with its top plate removed; Fig. 3 is a sectional elevation of the valve taken on line ,1k-y of Fig. 1; Fig. l is a sectional elevation of the same taken on line -ac of Fig. 2, Fig. 5 is a plan view of the locking detent plate removed from the spindle; and Fig. G is a plan view of the abutment and guide plate removed from the valve casing.

vided with the usual water tank. Secured to the bottom plate 3E1 of the tender tank (Figs. 1 and 3), is my improved valve G. The water from the tank is fed to the hose 7 under the control of the valve and by said hose is delivered to the injector 5, which delivers it into the boiler in the usual manner. The valve 6 is provided with an operating lever 10, which extends just below the sills of the tender body (Fig. 1), whereby the control of the valve may be easily had for shutting off or turning on the supply of water. irscreei 6L may be employed above the valve Referring now more particularly to the valve per se, 11 is a cylindrical body having a iange 16 at the top, by which it is secured by bolts 17 to the bottoni sheet 3l of the tender tank, the cylindrical body forming a well or pocket below the bottom of the tank and opening into the tank by a large aperture 3C (Fig. 3) of approximately the diameter of the interior of the body. rlhe body 11 has, at its lower portion, a transverse valve seat 12 having a thoroughfare 13 opening into a chamber 1i below the seat and provided with an obliquely arranged outlet nipple 15 to which the hose coupling connects. The upper portion of the interior wall of the body is formed with an annular shoulder 23, upon which a flange 29 of a plate 27 seats and to which it is clamped by the clamping screws 30a extending through apertures in the plate and screwed into the body. The bottom surface of this plate 27 is flat and acts as an abutment or thrust plate for the spring 26 of the spindle and for the swinging arm 24 for the valve piece 30; and moreover, this plate is provided with one or more apertures 272L for passage of water and preferably, one of these apertures is in direct alinement with the valve seat thoroughfare 13. The general construction of this plate 27 will be fully understood by reference to Figs. 3, 4l; and 6.

The valve seat 12 is oblong and the opening or thoroughfare 13 is arranged at one end so as to leave room at the other end for the valve piece when moved transversely to open the valve (Fig. 2). This thoroughfare 13 may be bored through a solid seat surface and in this way thevalve may be made right or left handed as desired, the chamber 14 below the seat being also oblong to include either of such openings.

All)

Arranged to one side of the valve seat is a spindle bearing 18, in` which the valve operating spindle 19 Vis journaled. rllhis spindle 19 has, on its inner end, a circular collar 20 and a polygonal-shaped part 23. rllhe collar 20 its into a recess 22 which contains packing rings 21 of copper or other ductile metal surrounding the spindle 19 and presses upon said rings to form a watertight joint. In place of these metal rings, other forms of packing may be employed where water is to loe controlled. The inner' end of, the spindle is. formed with a socket 25 in which a coiled spring 26 is placed, said spring pressing against the plate 27 and causing the collar 2O to press down tightly upon the packing rings. rlhe lower end of the spindle 19 is fitted with a lever 10 by which to rock it when actuating the valve piece 30.

2st isa swinging arm having a polygonal aperture through which fits the polygonal end 23 of the spindle-and by which the arm is given a swinging motion within the valve body. The free end of the arm 24, on its sidefacing the valve seat 12, is provided with an annular recess 32 and a central hub 34. A valve piece 30,- preferably circular in shape, rests upon the valve seat and has an annular* cylindrical flange 31 which telescopes with the recess 32 of the swinging arm, saidf connection acting to cause the valve piece to loe moved with the arm and thereby causedA to traverse the valve seat. A spring 33 is arranged within the recess 32 of the arm 24 and presses upon the valve piece toforce it upon its seat and at the same time force the arm against the under surface of the plate 27, as will be readily understood by reference to Fig. 4. The space between the valve piece and the central hub 34 on the arm 24: is sufficient to allow the said' valve piece to be forced upward from its seat by a superior under or back pressure, when desired, so as to act as a check valve. I have shown the preferred manner of connecting the valve piece with theV swinging arm, which permits a perfect sliding fit at small cost, but I do not restrict `myself'to'the details shown, as any other suitable connection may be employed so long as the valve piece is moved with the arm and may act as a check valve.

By oscillating the arm or lever 10, the spindle 19 is rocked andthe arm 24 oscillated for the purpose of shifting the valve piece 30 over the valve seat 12, and opening or closing the thoroughfare orifice 13. A suitable locking means may be provided for holding the spindle in its extreme positions of oscillation, the means shown consisting of a plate 35 fitted to the spindle so as to oscillate with it and having notches as 36 and 37 combinedwith a pivoted lock 38 hinged to the case 11 andaolapted for engagement with the notches 36 and 37 according to the position to be assumed by the valve piece. For example, when the valve is closed the parts are as indicated in Figs. 2 and l1-, and the lock 38 engages the notch 37 of the plate 35; and when the valve is in open position, the lock 3S engages the notch 3G of said plate From the foregoing description, it will be seen that the construction and assemblage of the valve structure is very simple and inexpensive; and from the nature of the construction, the sliding valve piece will insure atight lit with the valve seat because the parts have a regrinding effect by the natural operation of the valve piece over its seat. rhe plate 27 is perforated or so shaped as to permit free passage of water to the interior of the body and ready access to the thoroughfare 13 when uncovered. .By unpinning the lever or arm 10 and the locking plate and also removing the plate 27, the entire valve structure may be readily dismantled for cleaning or repairs.

As thebody 11 .is arranged directly upon the bottom of the tank and projecting below the same, it acts as a pocket or well for draining the tank completely, and by removing the hose, the tank may, from time to time, be flushed out through the valve to keep it in a clean condition, especially in those cases where the feed water is impure and sediment settles from it in the tank.

Where the water is allowed to remain in the hose 7 during cold weather and when the locomotive is out of commission, there being no way for draining said hose and its connections, the water is liable to freeze and much damage has heretofore been caused inthis manner. My improved valve enables the water in the hose to be blown back through the valve into the tank, when the locomotive is run into the round house or into the yard over night. To accomplish this, the locomotive may be provided with a-by-pass pipe 3, provided with a hand valve 9 for turning steam into the hose 7 and blowing the water Vtherein through the valve into the tank. When this superior steam pressure is applied to the discharge side of the valve, it forces the valve piece 30 up ward away from its seat and permits the upward flow of the water. The spring 33 is compressed untilA the valve piece 30 is brought against the hub or stop 3ft of the arm 2st andduring the action of the valve as a check-valve; and as soon as the .steam is shut offthe spring quickly forces the valve piece upon its seat and prevents the return of the water. ln this way, the hose is kept clear of water when the weather conditions make it desirable, but at all other times the water may be permitted to remain in the. hose as heretofore. ln many forms ol injectors in general use the steam may be permitted to blow back through the hose before the injector is adjusted to force the water into the boiler and in such cases the by-pass pipe 8 and valve 9 may be omitted and the injector alone relied upon.

l have shown the general construction and details of my improved valve device in the form l have found most desirable in com mercial practice, but do not wish to restrict myself thereto, as the details may be varied within reasonable limits without departing from the spirit of the invention defined in the claims.

ln this application l make no claim to the system comprising the use of the above described valve in connection with the locomotive and tender whereby the steam pressure of the locomotive may be employed to blow the water from the hose connection back through the valve into the tender tank, utilizing the valve as a check valve when it is desired to clear the hose of water in the winter time, as said system and combination of parts forms subject matter of a divisional application filed May 8, 1914, and Ser. No. 837,123.
